The origin of high-mismatch orientation relationships for ultra-thin oxide overgrowths
چکیده انگلیسی

A crystallographic orientation relationship (COR) of unusually high lattice mismatch (>15%) between an Al{1 0 0} substrate and its ultra-thin (<1 nm) oxide overgrowth is reported. This striking observation is in contrast with the general assumption that a COR with the lowest mismatch is preferred. However, as shown by thermodynamic model calculations, despite the relatively large energy contributions from residual strain and misfit dislocations, the high-mismatch overgrowth can be stabilized by a relatively low surface energy and a relatively high density of metal–oxygen bonds across the interface.
